    curs_insstr(3x)                                         curs_insstr(3x)

## NAME

           insstr,  insnstr,  winsstr, winsnstr, mvinsstr, mvinsnstr,
           mvwinsstr, mvwinsnstr - insert string before cursor  in  a
           curses window

## SYNOPSIS

           #include <curses.h>
           int insstr(const char *str);
           int insnstr(const char *str, int n);
           int winsstr(WINDOW *win, const char *str);
           int winsnstr(WINDOW *win, const char *str, int n);
           int mvinsstr(int y, int x, const char *str);
           int mvinsnstr(int y, int x, const char *str, int n);
           int mvwinsstr(WINDOW *win, int y, int x, const char *str);
           int mvwinsnstr(WINDOW *win, int y, int x, const char *str,
           int n);

## DESCRIPTION

           These  routines insert a character string (as many charac-
           ters as will fit on the line) before the  character  under
           the cursor.  All characters to the right of the cursor are
           shifted right with the possibility of the rightmost  char-
           acters  on  the line being lost.  The cursor position does
           not change (after moving to  y,  x,  if  specified).   The
           functions  with  n  as  the last argument insert a leading
           substring of at most n  characters.   If  n<=0,  then  the
           entire string is inserted.

           Special characters are handled as in addch.

## RETURN VALUE

           All  routines that return an integer return ERR upon fail-
           ure and OK (SVr4 specifies only "an  integer  value  other
           than  ERR")  upon  successful completion, unless otherwise
           noted in the preceding routine descriptions.

           X/Open defines no error conditions.  In  this  implementa-
           tion, if the window parameter is null or the str parameter
           is null, an error is returned.

## NOTES

           Note that all but winsnstr may be macros.

## PORTABILITY

           These functions are described in the XSI Curses  standard,
           Issue 4, which adds const qualifiers to the arguments.

           The  Single  Unix  Specification,  Version  2  states that
           insnstr and winsnstr perform wrapping.  This  is  probably
           an error, since it makes this group of functions inconsis-
           tent.  Also, no implementation of  curses  documents  this
           inconsistency.
